Molecular characterization and expression of a putative ATPase domain from Eimeria tenella

Abstract

VCP (Valosin-Containing Protein), a member of the AAA (ATPases Associated to a variety of cellular Activities) family of proteins, possesses a duplicated highly conserved ATPase domain. An expressed sequence tag (EST), representing a clone from the Eimeria tenella merozoite cDNA library, was found to have high similarity to VCP genes from other organisms. A complete sequence derived from the corresponding clone (designated eth060) shows amino acid identity of 42-62% with other members of the VCP subfamily. Sequence analysis identified a putative ATPase domain in the eth060 sequence. This domain was PCR-amplified using gene-specific primers and cloned into a pBAD/Thio-TOPO expression vector. Expression in Escherichia coli demonstrated that the putative ATPase domain, which consists of 414 amino acid residues, produced a fusion protein of approximately 60 kDa in size.
